MORGAN -- A 48-year-old motorcyclist from Mountain Green was killed Thursday night when he crashed on Interstate 84.
William Muse was driving his Harley-Davidson west on I-84 around 7:30 p.m. when "something strange happened" and he lost control of the motorcycle, said Utah Highway Patrol Trooper Brandon Whitehead.
"He veered to the left, went off the road ... (and) hit the guardrail, which threw him over the rail and he landed in the median" near Mile Marker 104, Whitehead said.
The impact caused severe trauma, shattering Muse's neck and pelvis, Whitehead said.
Emergency responders attempted to resuscitate Muse, but he was pronounced dead after being taken by ambulance to Ogden Regional Medical Center.
After Muse was thrown, the motorcycle continued another 1,200 feet, Whitehead said, adding it was a good thing someone saw the accident and called, because the motorcycle was barely damaged and came to rest upright, off the road.
It would not have been immediately obvious to look for the driver, he said.
Investigators are still trying to determine the cause of the crash.
Whitehead said his instinct was that a medical problem may have led to the crash, but an autopsy would have to provide a definitive answer on that.
Though Thursday's thunderstorms poured rain on UHP troopers investigating the accident, he said, the roads were dry at the time of the crash.
